FLUSH-VALVE.

Specication of Letters Patent.

Patented Dec. 2, 19119.

Application filed September 4, 1917. Serial No. 189,465.

To all whom z' may concern Betit known thais I, EDGAn J. BLOoM,`

a citizen of the United States, residing at Tiffin, county of Seneca, State of Ohio, have invented a certain new and useful Improvement in F lush-Valves, and declare the following to be a full, clear, and exact descrip` tion of the same, suc-l1 as will enable. others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to flush valves, and has for its object a Hush valve which has a. novel arrangement for adjusting the length of the flushing operation when the operating handle is held in operative position.

There are also other novel features of structure which will more fully appear in the description following and in the claims.

In the drawings,*

Figure l is a vertical section.

F ig. :2 is a vertical-section in a 90 degree position from the showing of Fig. 1.

Fig. 3 is, a view similar to Fig. l but fragmentar)v and showing the valve in open p0- sition.

Fig. 4. is a cross section on the line D-D of Fig. 2. y

Fig. 5 is an elevation of the flush valve applied to a water closet. y Fig. 6 is a detail of the relie-f lvalve dog. Fig. 7 is a detail or bottom view of the relief valve.

Fig. 8 is a detail of the handle.

Fig. 9 is an end elevation of the handle.

a designates the usual barrel of the flusher; b the cored intake passage; o the valve seat provided with a spider' d to guide the stem of the valve e. The valve e is a compound'piston valve, the lower portion acting as the inlet valve,'provided with the packing ring f and an annular fiange. g

that fits over the outside of the valve seat.

This outside flange is advantageous as it avoids the unpleasant hissing sound which accompanies the operation of so many valves, especially where the: rim fits to the inside of the'valve seat. The main body of the valve or the connection between the piston and the valve proper is in the form of a V h through one leg of which is a passage-Way i from the intake passagel to the chamber behind the piston. This allows the ingress of the water under pressure so that inasmuch as the area of the piston is greater parts of a relief a-bottom plan view showing that than the area of the valve proper, the valve always tends to close and remain closed.

he upper end of the V terminates in a 'neck or housing j internally threaded and arranged to house part of the operating valve, of which 7c is the threaded cap that fits into the threaded end of the neck y' and acts as an abutment for one end of the coil spring Z, which tends to .keep the relief valve m upon its seat. This relief valve is detailed in Fig. 7, which is it has guiding wings three in number.

Between the legs of the V is pivoted the dog n in a hole o. This dog is so balanced by gravity that it ordinarily bears against the bottom of the valve stem .2, as shown in F ig. l. However, if the outer end of the dog is pushed down, as shown in Fig. 8, it serves to raise the relief valve. This immediatelyreleases the pressure behind the piston-like valve, and the. pressure on the lower end of the valvenoiy serves to lift the large valve portion off of the seat, allowing the water to run through the valve seat and over its walls down through the outlet pipe 7) into the water-closet bowl, which is thereby flushed.

The tail of the dog is thrust down to raise the relief valve by movement of the operating lever g, which may be up, down or to either side, or in any intermediate direction. Any movement of the handle pushes in the plunger 1 as indicated in Fig. 8, depressing the tail of the dog and raising the relief valve. This movement is resisted by the coil spring s which serves both this function and the function of holding the washer and packing t properly seated.

he plunger stem and the plunger head may be disassembled by unscrewing them (Fig. l). It will be noted that the handle g is assembled with respect to the plunger by the nut u having a turned-in rim which forms a socket for the handle. A lock nut w serves to keep this nut u in any desired position of adjustment.l

Now referring to Fig. 8, the means for regulating the length of the flushing operation during actuation of the handlel will be seen. Now` obviously the amount of inward projection of the plunger depends upon the projection of the set screw v in the end of the handle. The farther this is turned out the farther in the lunger goes. ,The farther in' the plunger is ocated toward the dog n, the

farther the compound valve rises before the do drops o from the end of the plunger an allows the relief .valve to close and the closing operation of the compound valve to a follow. 1

`From this description it appears that the adjustment ofthe flushing operation isjve'ry simple. All that is necessary is to release the lock nut and retaining nut u, thereby disassembling the handle from the rest of the relief valve operating; parts. A screw-driver may The handle is made in the form of two nuts so that one may be tightened against.

' the otheig being a vjam nut .which may be tightened against thev end of the valve when the set screw "c has been adjusted to the proper position. 'lhi's is eected bythe use of a screw-driver in the slot/v (Fig. 9). What l claim is: v l. ln a iushing valve, the combination of a barrel, a compound valve reciprocating in said barrel provided at one end with a large w the other `end with a casing housing a 'small valve and having a a tripping device for valve portion and at V-like body portion, the small valve located in the opening of the center of the V, and a Ipassage-way from the inside of the valve to the outside of the lvalve through one of the legs of the ll.
